TwLng is Buffer for Content with six main features:
1. Post content to Twitter that is longer than 140 characters
2. Add content to a queue for posting later.
3. Add content to a 'circle' for posting later.
4. Schedule post times using a calendar.
5. Follow users / favorite tweets based on a query from a calendar view.
6. Save drafts.
A circle is a queue where items are not popped - when the pointer reaches the end of the queue, it is reset back to the first element.
